Caitlyn Jenner stunned the world last week with the reveal of her new name and body on the cover of Vanity Fair. She joins a spate of other transgender celebrities, from Orange is the New Black's Laverne Cox to Matrix co-director Lana Wachowski, who are bringing visibility to a long-neglected community.

Today, more people—at younger and younger ages—are identifying as transgender than ever before. In Chicago, many of those young people suffering from gender dysphoria—feeling trapped in the wrong body—are patients of Dr. Robert Garofalo. The 49-year-old pediatrician heads a two-year-old gender identity clinic in Lake View, part of Lurie Children's Hospital.

Garofalo is leading the way in the emerging field of transgender pediatrics, and he recounts his works in a new feature for Chicago magazine. As part of that story, Chicago spoke to several of "Dr. Rob's" patients about their own journeys. Here, four of them share their stories.
